I find it a bit weird that I find it intuitive how things like the Super Nintendo did their work, and how modern games and systems work, but comparing the hardware specs of the Dreamcast/PS2/XBox/Gamecube era to the best of their output is where my intuition struggles the most. Not that the games of the era stand up to modern stuff, even when upscaled and texture-packed etc. in an emulator, but how they did it with so little oomph still amazes me.
